Stalled/wants to stall at stop.
The other day while coming to a stop my truck lost throttle response, It was still idling but it would not respond when i hit the throttle. I shifted it to nuetral and back to drive and it worked. The next day came to a stop sign and it stalled out. restarted right away. now when i come to stop its acting like the engine is coming under load and the rpms drop abit(maybe 100rpm) and the idle kinda bounces up and down. I have checked my connections to the chip, pedal,ipr,and transmission..ive driven it without the chip and though i could not get it to stall today its acting like it coming under load when coming to a stop....any help would be appriciated. thx
truck is a 02 7.3 4x4 with a BTS.
